Abstract

L'invention concerne un procédé et un appareil de réglage de luminosité d'affichage, et dispositif électronique et un support de stockage. Le procédé consiste à : obtenir une valeur de luminosité cible, et une valeur de couleur de chaque pixel dans des données de pixel chargées à afficher (S202) ; régler la valeur de couleur de chaque pixel selon la valeur de luminosité cible pour obtenir une valeur de couleur réglée (S204) ; et effectuer une diffusion d'erreur sur les valeurs de couleur réglées pour obtenir une valeur de couleur soumise à la diffusion d'erreur, et afficher lesdites données de pixel au moyen de la valeur de couleur soumise à la diffusion d'erreur (S206). La valeur de couleur de chaque pixel est réglée au moyen de la valeur de luminosité cible, de sorte que la luminosité ne soit pas réglée par la mise sous et hors tension d'un écran, ce qui règle la luminosité sans dépendre du matériel ; la diffusion d'erreur est effectuée sur les valeurs de couleur réglées, afin d'éviter les problèmes de barres de couleur et de blocs de couleur causés par le réglage de valeurs de couleur.
